## What is CVE-2023-33276?

CVE-2023-33276 is a medium-severity cross-site scripting vulnerability in n/a, published on 30 Jun 2023. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

The web interface of Gira Giersiepen Gira KNX/IP-Router 3.1.3683.0 and 3.3.8.0 responds with a "404 - Not Found" status code if a path is accessed that does not exist. However, the value of the path is reflected in the response. As the application will reflect the supplied path without context-sensitive HTML encoding, it is vulnerable to reflective cross-site scripting (XSS).

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

What it is: CVE-2023-33276 is a medium-severity cross-site scripting vulnerability in n/a, published on 30 Jun 2023. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-33276 exists.

Affected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
